9. Microscopes

What type of microscopy uses a special condenser that only allows light scattered by the specimen to reach the objective lens and causes the specimen to appear bright?

This form of microscope is able to refract light off of the dense structures of a cell making them appear brighter than the gray background.

The microscope that increases contrast and allows the specimen to appear three-dimensional is the...
